How To Make This Sausage Green Bean Potato Casserole
Step 1: Preheat the oven to 400°F. Line a baking sheet with foil and spray lightly with nonstick spray or brush with a little oil.
Step 2: In a large bowl, combine the halved potatoes and fresh green beans.
Step 3: Add the sliced smoked sausage, garlic, and yellow onion to the bowl.
Step 4: Drizzle the olive oil over the mixture and toss well with your hands or tongs so everything is evenly coated.
Step 5: Spread the mixture in a single layer on the prepared baking sheet. Sprinkle evenly with kosher salt and freshly cracked black pepper.
Step 6: Bake for 25 minutes. Remove the pan and turn the mixture with a spatula, then return to the oven for an additional 15 minutes, or until potatoes are tender and edges are browned.
Step 7: Allow the casserole to rest for 5 minutes on the counter before serving.
Troubleshooting
Uneven Cooking
If the casserole cooks unevenly, make sure ingredients are spread in a single layer with similar-sized potato pieces. Stirring or turning halfway through helps promote even roasting.
Casserole Is Too Watery
Vegetables can release moisture while cooking. To reduce excess liquid, briefly blanch green beans or pat vegetables dry before tossing with oil.
How To Serve This Smoked Sausage, Green Beans, and Potatoes Casserole
Serve the casserole hot, straight from the pan. Garnish with chopped fresh parsley or a sprinkle of grated Parmesan for added brightness. It works well as a complete weeknight meal or as a main dish alongside simple sides such as Spanish-style rice, creamy mashed potatoes, or warm pull-apart garlic bread (note: names listed as serving ideas).
